Abstract

The invention relates to the technical field of cooling devices, in particular to an air cooler which comprises a shell internally provided with a cooling structure. The air blowing structure is movably arranged on the shell and has a first state that the air blowing structure moves to the side part of the cooling structure when a driving structure corresponding to the air cooler works normally so as to expose at least part of the cooling structure; and in the second state, when the driving structure corresponding to the air cooler stops working, at least part of the cooling structure is covered, so that air is introduced into the cooling structure. The invention provides the air cooler which always keeps a good cooling effect in a working state.

Description

technical field [0001] The invention relates to the technical field of cooling and cooling devices, in particular to an air cooler. Background technique [0002] The hydro-generator and generator-motor will generate a lot of heat during operation. Generally, the heat will be transferred to the air inside the motor through a specific structure, and the heat will be taken out of the motor through the circulating flow of air inside and outside the motor. After the heat in the air is transferred to the secondary cooling medium, the air temperature drops, enters the motor again to absorb heat, and circulates in turn, thereby realizing the cooling of the hydro-generator and the generator-motor. There are generally several air coolers for vertical hydro-generators and generator-motors, which are symmetrically distributed on the back of the stator iron core for secondary cooling of the hot air in the motor ventilation system. There is a cold water pipeline in the water-cooled air c...
